My Typescript, React Material UI Blogs and Posts app needs an implementation of the Material UI Community version of the React DataGrid. Featuring sorting, paging, filtering and searching. This is an example of the json data it will consume: [ { "id": "1", "img": "https://picsum.photos/800/450?random=1", "tag": "Engineering, Company", "title": "Revolutionizing software development with cutting-edge tools", "description": "Our latest engineering tools are designed to streamline workflows and boost productivity. Discover how these innovations are transforming the software development landscape.", "authors": [ { "name": "Remy Sharp", "avatar": "/static/images/avatar/1.jpg" }, { "name": "Travis Howard", "avatar": "/static/images/avatar/2.jpg" } ] }].

Nice — I’ll give you a ready-to-drop-in TypeScript + React component that uses MUI Community DataGrid (@mui/x-data-grid) and demonstrates:

• sorting (native grid sorting)
• paging (client-side with page size controls)
• filtering (column filters + a tag dropdown filter)
• searching (quick search / quick filter)
• custom renderers for image and authors

You can copy the files below directly into your app and adapt the styles/columns as needed.

• Searching: The GridToolbarQuickFilter provides the built-in quick-search across filterable columns. It matches cell content across displayed columns. For more advanced searching (e.g., search only title + description), you can implement a custom quick filter by controlling filterModel on the grid and using applyFilterInMemory or custom row filtering before passing rows (we use filteredRows for tag filtering already).
• Filtering: The example includes the toolbar filters (column filters) plus a custom Tag dropdown. For server-side filtering/paging, switch to controlled paginationModel, onPaginationModelChange, filterModel, and fetch page/filter on change.
• Sorting: DataGrid does sorting client-side by default. To sort server-side, use sortingMode="server" with controlled sortModel.
• Performance: For very large datasets, use server-side pagination or virtualization. The community DataGrid supports virtualization; ensure autoHeight / height are set properly and avoid rendering thousands of rows all at once.
• Styling: Tweak sx props or theme overrides to match your design system.

If you want, I can:

• Add server-side sample (controlled pagination + filter + sorting) with an example API mock.
• Add row selection and action column (edit/delete).
• Add column-level filtering UI (e.g., tag chips in the column filter) or highlight search matches in cells.

Which of those would help you next?

Many of these components are deprecated. For example, it is suggested to use Toolbar rather than GridToolbarContainer. THis is a full list of the deprecated components: GridToolbarContainer, GridToolbarExport, GridToolbarColumnsButton, GridToolbarFilterButton, GridToolbarDensitySelector, GridToolbarQuickFilter

Thought for 11 seconds

I need to check for the latest updates on the MUI DataGrid Community toolbar components because there might have been changes, particularly around GridToolbar or GridToolbarQuickFilter.

I'll search for the most accurate information on modern components as recommended by the current MUI library to ensure I’m implementing the best approach. So, it seems like a good idea to look up the latest version and compare it with the previous API to be sure!

It looks like MUI v8 has made some changes to the toolbar components. For instance, GridToolbar has been replaced by Toolbar, ToolbarButton, and a few others like QuickFilter and FilterPanelTrigger. The documentation now uses slots and slotProps instead of components. I need to produce an updated code example for v8, using the prescribed imports like ToolbarButton and QuickFilter. I'll also need to check the exact exports to make sure the implementation matches the updated toolbar API.

Done

Good catch — MUI X has moved away from the old GridToolbar* set and replaced it with the new Toolbar / QuickFilter / Trigger / PanelTrigger / ToolbarButton composition API (v8+). I checked the MUI docs and migration notes: the old GridToolbarContainer, GridToolbarExport, GridToolbarColumnsButton, GridToolbarFilterButton, GridToolbarDensitySelector, GridToolbarQuickFilter are deprecated and the recommended approach is to compose the toolbar with the new building blocks (Toolbar, ToolbarButton, QuickFilter, QuickFilterControl, QuickFilterTrigger, FilterPanelTrigger, ColumnsPanelTrigger, DensitySelector, export button component, etc.). MUI+2MUI+2

Below is an updated TypeScript + React implementation that:

• uses the new (v8+) toolbar composition API from @mui/x-data-grid (no deprecated GridToolbar* components),
• preserves sorting/paging/filtering/searching,
• includes a custom Tag dropdown filter (client-side),
• uses the QuickFilter composition for the quick search input.

Notes: imports come from @mui/x-data-grid (or @mui/x-data-grid/components where indicated by the docs). If you use a specific minor/major DataGrid version, adjust import paths if your bundler complains. (Docs show both @mui/x-data-grid and @mui/x-data-grid/components are valid entry points.) MUI+1

            <CustomToolbar {...props} tags={tags} tagFilter={tagFilter} onTagChange={setTagFilter} />
          ),
        }}
        // If you prefer to pass slotProps for built-in toolbar primitives, use `slotProps` here.
        initialState={{

    </Box>
  );
};

1. Exact exports vary slightly by minor version.
   The new toolbar primitives may be available from either @mui/x-data-grid or @mui/x-data-grid/components depending on your installed version. If your build complains about an export name (e.g., ExportButton), check the package's API docs or try importing from the components path. The MUI docs show both entry points. MUI+1
2. Slots vs components: v8+ uses slots and slotProps (rather than components / componentsProps) in many examples. Both may still work depending on your installed DataGrid version, but slots is the direction used in the new docs. Use slots={{ toolbar: MyToolbar }} to replace the toolbar. MUI
3. Quick filter composition: instead of GridToolbarQuickFilter, compose QuickFilter + QuickFilterControl + QuickFilterTrigger + QuickFilterClear — this gives full control and is the recommended path for custom toolbars. MUI
4. If you need backwards compatibility across several versions, you can create a small adapter that tries to import the legacy GridToolbarQuickFilter / GridToolbarContainer first and falls back to the new composition API — but this complicates bundle size and types. If you're on v8 or planning to upgrade, move to the new composition API.

If you want I can:

• Update the example to use server-side pagination / sorting / filtering (controlled models) with a mock API.
• Detect the installed DataGrid version and provide an adapter wrapper that exports a single AppToolbar component that works with either the old GridToolbar* or the new Toolbar primitives.
• Test/verify exact import names for your current @mui/x-data-grid version if you paste your package.json (I can check docs matching that version and give copy-paste-safe imports).

Which of those would you like next?

Lots of errors with the new BlogPostsGrid above. What is the most efficient method of communicating them to you

The most efficient way is to give me exactly what your TypeScript compiler or terminal is telling you — ideally:

1. Copy–paste the full error messages (with file/line numbers and the offending code snippet if possible).
2. If there are many, group them by type (e.g., "ExportButton not found", "ToolbarButton not assignable", etc.) so I can see patterns.
3. Include your package.json dependency versions for:
   • @mui/material
   • @mui/icons-material
   • @mui/x-data-grid
4. Mention your React + TypeScript versions — some APIs are gated by TS version or React version.

If you paste that, I can:

• See whether the errors are version mismatch (likely here — the new Toolbar API only exists in certain @mui/x-data-grid releases).
• Adjust the imports to exactly what your version exports.
• Provide a fixed version that runs without deprecated APIs and without errors.

Do you want me to give you a compatibility-safe BlogPostsGrid that works on both the current community DataGrid and the older one you have, so you can upgrade later without rewrites?

Thought for 10 seconds

The user shared their errors and package.json, asking for the most efficient way to communicate the issues. I need to analyze the errors, identify the root causes, and offer fixed code for compatibility with specific package versions: @mui/x-data-grid v8.9.2, @mui/material 7.3.1, React 19, and TS 5.8. Key issues include the ExportButton not being exported and the deprecated GridToolbarExport in v8. I'll need to use a web search to check for relevant updates for v8.9.2 and confirm the correct imports.

The web results show that the export feature is now accessed via the showToolbar prop, with components like Toolbar, QuickFilter, and Export available. However, TypeScript errors indicate that ExportButton is not exported. I need to either import Export from '@mui/x-data-grid/components' or use showToolbar with slots. To clarify the correct approach, I’ll review the docs, especially for customizing exports. It’s time to open the export page and dig deeper.

The page shows that ExportCsv and ExportPrint are now exported, so I should replace ExportButton with one of those. There’s also an issue with the sx prop not being recognized for Toolbar; the error suggests the Toolbar component is likely not an MUI Box. I’m wondering if using Box or MUI Stack to create the toolbar and manually adding the QuickFilter and Export components would be simpler. Lastly, I need to update pagination since pageSize is deprecated, switching to paginationModel and onPaginationModelChange.

Done

Thanks — this is exactly what I needed. Your package.json shows:

• @mui/x-data-grid: ^8.9.2 (v8 series)
• @mui/material: ^7.3.1
• React 19, TypeScript ~5.8

That explains almost all of the errors: v8 changed a number of APIs (slots/slotProps, paginationModel, new export components) and a few of the components/props in my previous snippet were incorrect for your installed version. I checked the v8 docs and examples to make the fixes below. MUI+1

1. ExportButton doesn't exist in v8 — use the specific export components: ExportCsv, ExportPrint (Excel export lives in premium). MUI
2. Toolbar component props typing — the grid Toolbar doesn’t accept the sx prop directly (typed narrowly). Wrap toolbar content in an MUI <Box> or cast appropriately. (Avoid adding sx directly to the grid Toolbar.) MUI
3. QuickFilterControl typing — it doesn’t accept sx directly. Wrap it in a Box or style the wrapper. Use the QuickFilter composition per docs. MUI
4. Grid pagination API changed — pageSize/onPageSizeChange are older props; v8 uses paginationModel + onPaginationModelChange. That explains the pageSize error. MUI
5. TypeScript generics / row typing — DataGrid was used without row generics, so some params.row got inferred incorrectly (the string / title errors). Use DataGrid<BlogPost> and GridRenderCellParams<ValueType, BlogPost> so params.row.title types-check.
6. Implicit any ESLint/TS errors — add explicit types for callback parameters.

This version:

• targets @mui/x-data-grid@^8.9.2 and @mui/material@^7.3.1
• uses paginationModel + onPaginationModelChange
• uses ExportCsv and ExportPrint from @mui/x-data-grid
• composes the new QuickFilter pieces correctly (wrapped so we can style)
• types the grid with BlogPost to remove string/title errors
• avoids sx on Toolbar itself (wraps content in Box)

• pageSize / onPageSizeChange errors: replaced by controlled paginationModel + onPaginationModelChange.
• Type 'string' does not satisfy GridValidRowModel / params.row.title errors: added the generic <BlogPost> on DataGrid and typed renderers GridRenderCellParams<..., BlogPost>, giving params.row.title a correct type.
• Implicit any ESLint/TS warnings: all callback parameters are explicitly typed (e.g., model from onPaginationModelChange).
• ESLint rule about unstable default props: keep pageSizeOptions as a variable in the props rather than recreating arrays inline when you pass defaults (you already pass pageSizeOptions as a prop, so you should be fine; if linter complains, move the array out to a const).

• Run a local compile-check: paste the exact TypeScript/TSConfig or any additional errors if any remain and I’ll iterate.
• Add row actions (edit/delete) with a menu and callbacks (typed).
• Make the grid server-side (controlled filtering/paging/sorting) with a small mock API implementation (useful for large datasets).
• Create an adapter toolbar that tries to import older GridToolbar* components if present (helpful if you plan to support multiple codebases/versions).

Tell me which of those you want, or paste any remaining VS Code error messages and I’ll fix them precisely.

Thought for 13 seconds

I need to respond with the necessary fixes for these errors, which seem related to wrong imports and types. The API for @mui/x-data-grid v8.9.2 has changes, such as the renaming of DensitySelector to gridDensitySelector, and ExportCsv and ExportPrint might now be GridExport. I’ll inspect the local package, but since the developer suggested using web.run to check for any recent changes to MUI, I’ll run a couple of queries to verify the latest API.

In v8, some components have changed names, like the DensitySelector, which is now the gridDensitySelector hook. I could skip this and use built-in props like showToolbar or create a custom toolbar for simplicity. There are also type errors in the existing code, like incorrect handling of rows and variables. My suggestion: remove the DensitySelector import, and use ColumnsPanelTrigger and FilterPanelTrigger instead, as they seem available. I’ll also replace it with a button that sets density using the apiRef.

Done

Thanks — this is perfect info. You hit real API/typing mismatch problems (some v8 exports differ, and my previous sample mixed a few primitives that your installed @mui/[email protected] doesn’t export). The fastest, most robust fix is to simplify: use the built-in showToolbar (which gives export + quick filter + column/density/filter panels) and keep the custom Tag dropdown outside the toolbar. That sidesteps the spotty named exports (e.g. no DensitySelector exported directly in your version) while still giving you sorting, paging, filtering and searching. I’ll also fix all TypeScript generics so params.row and params.value types are correct and remove any implicit any params.

Below is a compact, compatibility-safe version tailored to your stack (@mui/x-data-grid@^8.9.2, @mui/material@^7.3.1, React 19, TS ~5.8). It:

• removes DensitySelector / ExportButton usage (uses showToolbar to enable the default toolbar UI),
• types the DataGrid<BlogPost> so params.row.title and similar access are correct,
• uses the paginationModel API (v8),
• places the Tag dropdown above the grid (not as a composed toolbar element) so we don't rely on the toolbar composition primitives that differ across micro-versions,
• avoids nested component definitions where ESLint complained (Toolbar is not nested in rendering).

Copy this into BlogPostsGrid.tsx and it should clear the majority of those VS Code errors:

export default BlogPostsGrid;

• No DensitySelector import: removed — your version doesn’t export a direct DensitySelector component. Using showToolbar gives the user density/columns/filters UI without relying on the exact export names. (Docs indicate showToolbar exposes the default toolbar with those controls.) MUI+1
• All DataGrid renderers are typed with DataGrid<BlogPost> and GridRenderCellParams<..., BlogPost> so params.row.title and params.value types are correct and the "string vs GridValidRowModel" errors go away.
• Box component="img" usage fixed: src receives a string | undefined (not a BlogPost object) because renderCell generics ensure params.value is typed correctly. That removes the overload/type errors.
• No nested component definitions for toolbar primitives (avoids ESLint complaint). The tag dropdown is a top-level control above the grid.
• Pagination API uses paginationModel / onPaginationModelChange, matching v8.9.2.
• No implicit any: callbacks like onPaginationModelChange have typed parameters.

• If you do want a fully custom toolbar (so the Tag filter lives inside the toolbar and you control the quick filter appearance), I can produce a minimal adapter that checks which primitives exist in your installed package and uses the appropriate imports — I’ll need your node_modules/@mui/x-data-grid/package.json version or I can infer from your package.json (you already gave it). That’s slightly more code but doable.
• If you prefer the Tag filter as part of the toolbar, say so and I’ll generate a stable adapter that either uses slots.toolbar (v8 style) or falls back to a container component when primitives are missing.
• If you paste the fresh VS Code Problems list after you replace the file with the new snippet, I’ll iterate until all red errors are gone.

Would you like the Tag filter inside the toolbar (custom toolbar) or keep it as-is above the grid? If inside, I’ll create a version that uses slots.toolbar + guarded imports (detecting available exports) so it works with your exact v8.9.2.

Every column has a problem with the rendercell definition. This line: renderCell: (params: GridRenderCellParams<string | undefined, BlogPost>) causes the error: Type 'string | undefined' does not satisfy the constraint 'GridValidRowModel'. Type 'undefined' is not assignable to type 'GridValidRowModel'.

Thought for a few seconds

Okay, I need to fix the typing issue with GridRenderCellParams. It seems like in MUI v8, the correct order for the generics is GridRenderCellParams<TRow, TValue>, meaning TRow is the first generic. The error suggests it's expecting GridValidRowModel in the first generic, so I'll flip them. I thought GridRenderCellParams<string, BlogPost> worked, but there were earlier issues. I should correct it to GridRenderCellParams<BlogPost, string | undefined>. I'll also investigate the pageSizeOptions prop issue to make sure it’s correct.

Done

Nice catch — that error comes from the type parameter order for GridRenderCellParams in your installed @mui/x-data-grid (v8). I used the wrong generic order in the previous snippet, so TypeScript tried to use string | undefined where it expected a GridValidRowModel (the row type).

Flip the two generics. Use the row type (BlogPost) first, and the cell value type (string | undefined, Author[] | undefined, etc.) second.

For example, change this (wrong):

renderCell: (params: GridRenderCellParams<string | undefined, BlogPost>) => { ... }

to this (correct for v8):

renderCell: (params: GridRenderCellParams<BlogPost, string | undefined>) => { ... }

Or — simpler — remove the explicit generics entirely and let TypeScript infer types from DataGrid<BlogPost>. That often reduces friction.

The GridRenderCellParams generic type in v8 expects the row model as the first generic parameter and the cell value as the second. My earlier code swapped them, so TS complained that the first generic (string | undefined) was not a valid row model.

Below are the corrected renderCell signatures for the columns in the last version I gave you. Replace your columns definitions' renderCell types with these (or remove the generic parameters entirely if you prefer inference):

// import Author type from your types file
import type { BlogPost, Author } from "./types";

// ... inside columns array:

{
  field: "img",
  headerName: "Cover",
  // ...
  renderCell: (params: GridRenderCellParams<BlogPost, string | undefined>) => {
    const src = params.value;
    return src ? (
      <Box
        component="img"
        src={src}
        alt={String(params.row.title ?? "")}
        sx={{ width: "100%", height: 80, objectFit: "cover", borderRadius: 1 }}
      />
    ) : (
      <Box sx={{ width: "100%", height: 80, bgcolor: "grey.100", borderRadius: 1 }} />
    );
  },
},

{
  field: "tag",
  headerName: "Tags",
  // ...
  renderCell: (params: GridRenderCellParams<BlogPost, string | undefined>) => {
    const tagString = params.value ?? "";
    const tagList = tagString.split(",").map((t) => t.trim()).filter(Boolean);
    return (
      <Stack direction="row" spacing={1} flexWrap="wrap">
        {tagList.map((t) => (
          <Chip key={t} label={t} size="small" />
        ))}
      </Stack>
    );
  },
},

{
  field: "description",
  headerName: "Description",
  // ...
  renderCell: (params: GridRenderCellParams<BlogPost, string | undefined>) => (
    <Typography /* ... */>{params.value}</Typography>
  ),
},

{
  field: "authors",
  headerName: "Authors",
  // ...
  renderCell: (params: GridRenderCellParams<BlogPost, Author[] | undefined>) => {
    const authors = params.value ?? [];
    return (
      <Stack direction="row" spacing={1} alignItems="center">
        {authors.slice(0, 3).map((a) => (
          <Avatar key={a.name} src={a.avatar} sx={{ width: 28, height: 28 }} alt={a.name} />
        ))}
        {authors.length > 3 ? <Typography variant="caption">{`+${authors.length - 3}`}</Typography> : null}
      </Stack>
    );
  },
},

1. Let the compiler infer:

   renderCell: (params) => {
     const src = params.value as string | undefined; // cast if needed
     ...
   }

   No generics, fewer type headaches.
2. Type the columns array thoroughly using GridColDef<BlogPost, TValue> generics (more typing but precise). Example:

   const columns: GridColDef<BlogPost, string | undefined>[] = [ ... ];

   Then renderCell can use simple (params) => ... with correctly inferred types.

If you want, I can:

• Patch your full BlogPostsGrid.tsx and paste the entire corrected file (with all generics fixed), or
• Paste a version that strips explicit generics and relies on inference (shorter), or
• Fix the remaining errors you still see after this change if you paste the updated VS Code Problems list.

Which would you prefer?

Down to 4 problems now. This line: {authors.slice(0, 3).map((a) => ( causes the error: Property 'map' does not exist on type 'string | never[]'. Property 'map' does not exist on type 'string'.ts(2339

This error means that TypeScript thinks authors could be either a string or an empty array (never[]), and since string doesn’t have .map(), TS complains.

You defined authors as either string | Author[] (or string | never[]), but your code assumes it’s always an array.

Make sure authors is always typed as an array of Author, or at least narrow its type before calling .map.

Your BlogPost interface should have something like:

interface Author {
  name: string;
  avatar: string;
}

interface BlogPost {
  // ...
  authors: Author[]; // Make sure it’s not string or undefined here!
  // ...
}

If authors can sometimes be undefined or a string, do this inside your renderCell:

renderCell: (params: GridRenderCellParams<BlogPost, Author[] | undefined>) => {
  // Force authors to always be an array
  const authors = Array.isArray(params.value) ? params.value : [];

  return (
    <Stack direction="row" spacing={1} alignItems="center">
      {authors.slice(0, 3).map((a) => (
        <Avatar key={a.name} src={a.avatar} sx={{ width: 28, height: 28 }} alt={a.name} />
      ))}
      {authors.length > 3 ? <Typography variant="caption">{`+${authors.length - 3}`}</Typography> : null}
    </Stack>
  );
},

If you want to be even safer:

function isAuthorArray(value: unknown): value is Author[] {
  return Array.isArray(value) && value.every(item => typeof item === 'object' && 'name' in item && 'avatar' in item);
}

Then:

const authors = isAuthorArray(params.value) ? params.value : [];

If you want, share your BlogPost type definition, and I can help you fix that too!

Authors is now always an array, but this line {authors.slice(0, 3).map((a) => ( returns the error: Property 'map' does not exist on type 'string | never[]'. Property 'map' does not exist on type 'string'

Got it — the error says authors is still typed as string | never[] somewhere, so TS thinks it might be a string, which has no .map().

Since you said authors is always an array now, it means the variable or parameter you're accessing still has a union type including string — so TS is warning you.

1. Double-check the type of authors at the exact place where you do .slice(0, 3).map().
   You can hover in your editor or add an explicit type assertion.
2. Make sure authors is typed explicitly as Author[] (array), not string | something.

If you get authors from params.value (e.g. in renderCell), make sure to narrow or assert its type like this:

const authors = params.value as Author[];  // assert type is Author[]

// or better, check before using:
const authors = Array.isArray(params.value) ? params.value : [];

• The DataGrid column's type might be declared as string | Author[] or similar, causing TS confusion.
• You might have authors property typed as string | Author[] somewhere in your BlogPost interface.

• Check your BlogPost interface: ensure authors is typed as Author[] only.

interface BlogPost {
  // ...
  authors: Author[]; // no union with string here
}

• If you can't change that, then always cast or narrow the value before using .map.

If I declare the authors variable like this: const authors: Author[] = Array.isArray(params.value) ? params.value : []; The problem goes away.Is that code safe if params is null for example?

Great question! The line:

const authors: Author[] = Array.isArray(params.value) ? params.value : [];

is safe only if params and params.value are guaranteed to be defined (not null or undefined).

If params could be nullish, then accessing params.value directly will throw a runtime error.

To make it safe regardless, you can do:

const authors: Author[] = Array.isArray(params?.value) ? params.value! : [];

• The optional chaining (params?.value) safely handles params being null or undefined.
• The non-null assertion (params.value!) tells TypeScript that params.value is not null when you use it after the check.

const authors: Author[] = params && Array.isArray(params.value) ? params.value : [];

• If params cannot be null or undefined (e.g., guaranteed by your function signature), your original code is fine.
• If params might be null or undefined, use optional chaining or a null check before accessing .value to avoid runtime errors.

If you want, I can help write a fully safe version for your exact code! Just let me know.

One error left. The line disableSelectionOnClick in the DataGrid configuration causes the error: Type '{ rows: BlogPost[]; columns: GridColDef[]; showToolbar: true; pagination: true; paginationModel: GridPaginationModel; onPaginationModelChange: (model: GridPaginationModel) => void; pageSizeOptions: number[]; disableSelectionOnClick: true; sortingOrder: ("asc" | "desc")[]; initialState: { ...; }; }' is not assignable to type 'IntrinsicAttributes & Omit<Partial<DataGridPropsWithDefaultValues> & DataGridPropsWithComplexDefaultValueBeforeProcessing & DataGridPropsWithoutDefaultValue<...>, DataGridForcedPropsKey> & { ...; } & RefAttributes<...>'. Property 'disableSelectionOnClick' does not exist on type 'IntrinsicAttributes & Omit<Partial<DataGridPropsWithDefaultValues> & DataGridPropsWithComplexDefaultValueBeforeProcessing & DataGridPropsWithoutDefaultValue<...>, DataGridForcedPropsKey> & { ...; } & RefAttributes<...>'. Did you mean 'disableRowSelectionOnClick'

The error message is telling you that the DataGrid component no longer accepts the prop disableSelectionOnClick. Instead, it suggests disableRowSelectionOnClick.

This is a breaking change in newer versions of MUI X Data Grid where the prop name was renamed.

Replace

disableSelectionOnClick={true}

with

disableRowSelectionOnClick={true}

• disableSelectionOnClick was deprecated/removed.
• The new prop is called disableRowSelectionOnClick.
• This change reflects clearer naming, focusing on disabling row selection on click events.

<DataGrid
  rows={rows}
  columns={columns}
  showToolbar={true}
  pagination={true}
  paginationModel={paginationModel}
  onPaginationModelChange={setPaginationModel}
  pageSizeOptions={[5, 10, 20]}
  disableRowSelectionOnClick={true}  // updated here
  sortingOrder={['asc', 'desc']}
  initialState={{ ... }}
/>

That should fix the last error! If you want, I can help double-check the rest.

My app has a BlogPostService which is instantiated with const svc = useBlogPostService(); and which exposes an async getAll method which is called as in: useEffect(() => { svc!.getAl() .then((posts) => { setPosts(posts); }) .catch((err) => setError(err.message)) .finally(() => setLoading(false)); }, [svc]);. Show me the DataGrid in a Blog page consuming posts from this service

Got it! Here’s a simple React functional component for a Blog page that uses your BlogPostService to fetch posts and renders them in a MUI DataGrid.

• useBlogPostService is a custom hook returning your service instance.
• svc.getAll() is an async function returning an array of BlogPost.
• You have MUI’s DataGrid and React set up.

import React, { useEffect, useState } from 'react';
import { DataGrid, GridColDef, GridPaginationModel } from '@mui/x-data-grid';
import { useBlogPostService } from './services/BlogPostService'; // adjust import path
import { CircularProgress, Typography, Box } from '@mui/material';

interface BlogPost {
  id: string;
  title: string;
  author: string;
  publishedDate: string;
  // add other fields as needed
}

export default function Blog() {
  const svc = useBlogPostService();

  const [posts, setPosts] = useState<BlogPost[]>([]);
  const [loading, setLoading] = useState(true);
  const [error, setError] = useState<string | null>(null);

  // For pagination (optional)
  const [paginationModel, setPaginationModel] = useState<GridPaginationModel>({
    page: 0,
    pageSize: 10,
  });

  useEffect(() => {
    if (!svc) return;

    setLoading(true);
    svc.getAll()
      .then((posts) => setPosts(posts))
      .catch((err) => setError(err.message || 'Failed to fetch posts'))
      .finally(() => setLoading(false));
  }, [svc]);

  // Define columns for the DataGrid
  const columns: GridColDef[] = [
    { field: 'id', headerName: 'ID', width: 100 },
    { field: 'title', headerName: 'Title', flex: 1, minWidth: 200 },
    { field: 'author', headerName: 'Author', width: 150 },
    { field: 'publishedDate', headerName: 'Published', width: 150 },
  ];

  if (loading) {
    return (
      <Box display="flex" justifyContent="center" mt={4}>
        <CircularProgress />
      </Box>
    );
  }

  if (error) {
    return (
      <Typography color="error" mt={4} align="center">
        {error}
      </Typography>
    );
  }

  return (
    <Box height={600} width="100%" mt={2}>
      <DataGrid
        rows={posts}
        columns={columns}
        pagination
        paginationModel={paginationModel}
        onPaginationModelChange={setPaginationModel}
        pageSizeOptions={[5, 10, 20]}
        disableRowSelectionOnClick={true}
        sortingOrder={['asc', 'desc']}
        getRowId={(row) => row.id}
      />
    </Box>
  );
}

• Uses useEffect to call svc.getAll() on mount.
• Tracks loading and error states to show a spinner or error message.
• Sets up basic columns (id, title, author, publishedDate).
• Enables pagination with controlled state paginationModel.
• Uses disableRowSelectionOnClick per your previous question.
• Uses getRowId to tell DataGrid the unique key is id.

If you want, I can help customize columns or add features like filtering, sorting, or toolbar!

Remember items in the post array have this format: { "id": "1", "img": "https://picsum.photos/800/450?random=1", "tag": "Engineering, Company", "title": "Revolutionizing software development with cutting-edge tools", "description": "Our latest engineering tools are designed to streamline workflows and boost productivity. Discover how these innovations are transforming the software development landscape.", "authors": [ { "name": "Remy Sharp", "avatar": "/static/images/avatar/1.jpg" }, { "name": "Travis Howard", "avatar": "/static/images/avatar/2.jpg" } ] }

Thanks for the detailed shape! Given that, here’s an updated version of the DataGrid setup that better fits your BlogPost structure:

• Shows image as a thumbnail in one column
• Shows tags (comma-separated)
• Shows title
• Shows description (maybe truncated)
• Shows authors — rendering their names with avatars as a small list inside the cell

import React, { useEffect, useState } from 'react';
import { DataGrid, GridColDef, GridRenderCellParams, GridPaginationModel } from '@mui/x-data-grid';
import { Box, Avatar, Typography, Tooltip } from '@mui/material';
import { useBlogPostService } from './services/BlogPostService';

interface Author {
  name: string;
  avatar: string;
}

interface BlogPost {
  id: string;
  img: string;
  tag: string;
  title: string;
  description: string;
